About

Avena strigosa (also called lopsided oat, bristle oat or black oat; syn. Avena hispanica Ard.) is a species of grass native to Europe. It has edible seeds and is often cultivated as animal feed in Portugal and Brazil. It is the only 14-chromosome species of the seven in existence that is grown for profit (though on small land areas). It is sometimes reported as a weed.

Uses

Avena strigosa used to be cultivated as human food in Scotland, but it is now cultivated as a forage for ruminants in South America. It is a nutritive grass with a good protein content.
